Question

Calculate weight of Co having same no.of oxygen atoms as are presented in 20 gram of Co2

Answer 1

22 g of carbon dioxide is 0.5 moles (22/44). Each mole of carbon dioxidecontains 2 moles of oxygen atoms, so this contains 1 mole of oxygen atoms. Each mole of CO contains 1 mole ofoxygen atoms, so this is the amount we want. 1 mole of CO is 28 g (12+14).
